Title: 0verkill Game Client Multiple Local Buffer Overflow Vulnerabilities
Severity: HIGH
Description:
0verkill is a client-server game. It is available for the Linux, OS/2 and Windows operating systems.
The 0verkill game client has been reported prone to multiple instances of exploitable buffer overrun vulnerabilities. The functions that have been reported to be affected are load_cfg(), save_cfg() and send_message(). These functions are implemented in client.c. It has been reported that due to a lack of sufficient boundary checks performed on data contained in HOME environment variables, a local attacker may overrun a 256 bytes stack based buffer. Additionally excessive data supplied as values for the players name and also the hostname, may also be used to corrupt sensitive process memory. Finally, the potential buffer overflow reported to exist in the network 'chat' routines may be exploited to overwrite 2 bytes of data beyond the affected buffer.
An attacker may exploit any one of these issues to potentially execute arbitrary instructions in the security context of the 0verkill game client.
Affected Products:
- 0verkill 0verkill 0.16.0
